Russell was killed in the line of duty Saturday in Afghanistan. Russel and Army Capt. Joshua Lawrence were inside a small command post on an Afghan army base, when an exploding grenade was followed in seconds by bursts of gunfire. Before any of the Americans could raise a hand to defend themselves, Lawrence was dead, one 5.56mm bullet to the head, and Russell was dying, shot three times in the back.
